Bridging Bash and .NET: Harnessing CurlDotNet for Linux-Compatible REST API Magic
It’s 2 AM on deployment night, and I’m staring at a cURL example from Stripe’s docs.
You know the moment — a dozen browser tabs open, half-written unit tests, and now I’m translating a curl command into C#. Again.
API docs everywhere default to curl. Stripe, GitHub, Twilio, OpenAI — they all hand you a Bash-friendly snippet and expect you to mentally map:
-
-Hbecomes a header object -
-dbecomes JSON content -
-ubecomes basic auth - Oh, and don’t forget that one weird header that silently breaks everything if you miss it
If you’re building C# apps on Linux, the friction gets real. We love Bash. We love .NET. But the two ecosystems don’t always shake hands naturally.
This article is about fixing that — bringing Bash and C# into harmony for Linux-friendly REST API work. And CurlDotNet is our bridge.
Bash & cURL: The DevOps Native Language
Bash and cURL are the lingua franca of API examples. Every service uses them because:
- They run anywhere with POSIX tools
- They prototype APIs fast
- They work beautifully on Linux servers, containers, pipelines
- You can copy, paste, tweak, and run instantly
On Linux, cURL is the closest thing to a universal API client.
The C# Reality
C# has fantastic HTTP libraries — but historically, .NET lived on Windows.
Now we have .NET 6+, container workflows, VS Code, and Linux-native tooling.
Still, the cultures differ:
- Bash users prefer pipes, one-liners, and curl
- C# devs prefer structure, classes, SDKs, and types
CurlDotNet brings them together so you can enjoy both.
Look at any major developer-focused platform:
- Stripe – curl everywhere for payments
- GitHub – curl examples for repositories, issues, workflows
- Twilio – curl for SMS, calls, verification
- OpenAI – curl for every model example
- Kubernetes – its API is REST; curl is the norm
- Postman – often shows curl right next to its collection links
If you want to follow the tutorial exactly as written, you’re starting with Bash.
.NET is now a fully cross-platform citizen:
- Runs on Linux servers
- Plays nicely inside Docker
- Works in CI/CD pipelines
- Talks natively to POSIX tooling where needed
A Linux-friendly approach to API calls means:
- Your code works on the same machines that run your scripts
- You can mix Bash and C# without translating mental models
- DevOps pipelines become simpler and more maintainable
Any solution — including CurlDotNet — needs to honor that.
What It Is
CurlDotNet is a .NET library that lets you:
Paste curl commands directly into C# and run them.
No translation.
No re-writing into HttpClient.
No forgetting headers.
No “why does this example work in Bash but break in C#?”
You paste this:
bash
curl -X POST https://api.stripe.com/v1/charges \
-u sk_test_123: \
-d amount=2000 \
-d currency=usd
